- lI/fUNITEn STATES PATENT ornion CHARLES BEN BORGESON, OF BUTLER, PENNSYLVANIA.

HEDDLE-MAKING MACHINE.

To all whom it may concern: 1 Be it known that LCnARLEs BEN BORGE- SON,13. cltlzen of the United. States, residing at Butler, in the county of Butler, State of Pennsylvania, have invented a new and useful Improvement in Heddle-Making Ma- 2 chines, of which the following is a specification. 1

My invention relates to a machine for makmg loom-heddles of a du lex' wire composed of two'parallelstrands so dered together continuously throughout their length; and the obj ect'of my invention ist'o provide an automatic power-dr1ven mach1ne,wh1ch 1s simple of construction, easy to keep 1n worklng order, andofgreat'capacity.

Y A further object of my invention is to, by a series of manipulations, producefree from any roughness which would injure the warp-threads of the loom e finished heddles, which are threaded onto two rods, from "which the heddles may easily and quickly be transferred to other rods or cords. This will I I save much time and work in getting the heddles ready for shipment, and also in stringing them on a loom harness.

To these ends my invention consists of the parts and combinatlons of parts, as herein- 1 afterdescribed, and more particularly pointed out in'theclaims at the end of this specification'.

Referring to the annexed drawings, Figure 1 is a front elevation of the complete machine.

and 13 are enlarged-side and edge views of a clamping disk for holding the ends of the heddle wires. Figs. 14, 1 1 and 14* are detail views of the front and opposite sides of a central disk carrying the central twisting pinions and forks supporting the wire clamping devices. Fig. 14 is a section through the pinion. Figs. 15 and 15" are views at right angles to each other of the central twistingpinions and their pivoted punches for opening the central eye of the heddle. Figs. 16 and 16 are views of the lower parts of an anvil which supports the heddle wire, while the punch presses itself between the two strands of the heddle wire to form the central eye. Fig. 17 shows side and edge views of the die which bends around the ends of the wire to produce the end loops of the heddle. Fig. 18 shows the heddle wire in position in relation to the die and coacting parts to form the heddle loop. Fig. 18 shows the same parts with the bending completed, and the end of the wire ready to be clamped before twisting commences. Figs. 19 and 19 are front and side views of the wire cutting device. Fig. 20 represents a front and end viewof a part of the central wire guide. Fig. 21 represents front and opposite end views showing the construction of the first guide through which the wire enters. Fig. 22 shows a spring seated journal for the axle carrying the wire feed Wheel. Fig. 23 is a piece of the duplex heddle wire from which the heddles are made. Fig. 24 is a partly completed heddle, and Fig. 25 shows a finished heddle threaded onto the storage rods 208.

In a complex machine like this, it will be helpful to a clear understanding, to give first a brief description of its general construction and operation before going into its details of construction.

Referring to Fig. 2, which shows a plan view of the entire machine, it will be seen that the general shape of the main frame is an elongated rectangle with an offset from its middle projecting at right angles. On the front rectangular portion are performed the operations of feeding and cutting off the wire into suitable lengths, punching a central warp thread eye in the same, and forming loops at the ends of the cut off section and twisting the duplex wire on each side of the central eye and at the end loops. These operations being completed the formed heddles are delivered to the rear offsetting portion of the machine, where they are received on endless carrying chains and are successively carried by the chains through a chemical flux bath and a soldering bath to solder the twisted portions of the wire, and the heddles are then automatically strung, by their end loops, upon storage rods for convenient storage and adjustment to the harness of the loom. The wire feeding devices are seen on the left hand end of Figs. 1 and 2 where a cone friction feed drives the wire feed wheels operating upon the wire 10, the cone feedbeing adjusted as to speed and the gears for driving the same being formed as hereafter described with blank spaces to give an intermittent feed which stops long enough to permit the cutting off operation to take place. The cut off lengths of wire are successively fed to a rotary carrier supporting punching and twisting apparatus mounted on a shaft parallel to the feed of the wire, and which punching and twisting apparatus takes a continuous succession of wire sections in parallel positions to each other and carries them laterally, or at right angles to their length, toward the rear over a circular path, during which travel all the punching and bending operations are successively performed on the wires and the heddles delivered in a continuous series to the soldering apparatus in the rear. It is the lateral travel of the wires in their rotary carrier which is made to perform successively the several twisting operations and in this way a plurality of wires are being acted on at the same time, which greatly increases the efliciency and capacity of the machine. With this general description, I will now proceed to a detailed description of the construction and arrangement of the various parts.

Referring to the drawings, Figs. 1, 2, 3, 4, the numeral 1 designates a frame supported by legs 2. On the frame is mounted the bearings 3 (Fig. 2) supporting the axle 4, which carries the tight and loose pulleys 5 and 6, the driving pinion 7 and the cam 8, Fig. 3. Two bearings 9 (Fig. 2) support shaft 10, to which are secured the driven wheels 11, at one end and the gear wheels 12, 13 and 14 at the other end, and disks 15, 16, 16 and 17 in the middle. Supported by bracket 18 and bearing 19 is a shaft 20 on which is fixed pinion 21 and the longitudinally adjustable driving cone 22, provided with a hub 23 around which is wound a spring 24, bearing against the cone and washer 25, which latter is pressed against the spring by the adjustable screw nut 26. Against the journal box 1.9 bears a collar 27 on the shaft. This shaft is threaded to allow cone 22 an adjustment for change of speed, when change of wire feed is wanted. Shaft 20 has a keynot shownwhich causes cone 22 to revolve rigidly with the shaft. In brackets 18 and 28 is j ournaled a transverse shaft 29, on the end of which is fixed the wire feed-wheel 30 and the longitudinally adjustable friction cone 31, against which presses the nut 32. Shaft 29 has a collar 33 bearing against bracket 28 and said shaft 29 is threaded to allow adjustment of the cone 31,

when different wire feed is wanted. This cone 31 also has a keynot shownwhich causes the cone to revolve with the shaft. The bracket 28, see detail Fig. 22, has an opening 34 in which turns shaft 29 against which bears block 35 pressed down by spring 36 operated by thumb screw 37 working in detachable bridge piece 38. Thus can the feed wheel 30 be made to press properly on the wire passing between it and the subjacent friction roller 39 (see Fig. 1) revolving on a pin 40 mounted in the frame as shown.

I will now describe the devices in the middie of the machine for successively carrying the wire section laterally to the rear and forming the eye and end loops. In the periphery of the two disks 15, see Figs. 1, 2, 5 and 6, are journaled the shafts 41, each of which at one end carries a geared pinion 42 and a spring disk 43; (helical springs can be used instead of spring disk) which spring disks are pressed against the pinion by nuts 44. At the other end of each shaft is mounted the twisting finger 45, see Figs. 1, 2, 5, 12, 12

and 12*, provided with a shank 46, a circular recess 47 and a hole 48 through which passes a flattened pin 49 provided with a rigid head 50 having bearing surfaces 51 and 52. The pin 49 is pivoted to the spring 53 secured to 45. In the twisting finger is inserted a plate 54 provided with a cam groove 55. To the twisting finger is fixed a wire guide 55. To one disk 15 are fixed levers 56, see Figs. 5, 19 and 19. Frame 1 has slots 56 and 57, see Figs. 1 and 2 to provide for lateral adjustment of bridges 58 and 59 and theirattached plates 60 and 61, see Figs. 1, 2, 5 and 6. To the bridges 58 and 59 are fixed the disks 62 provided with teeth to turn pinions 42 two or three revolutions. The disks have central hubs 62 in which the main axle 10 can turn freely. Plate 60 has a slot 63, (Fig. 18), a rib 63 and aprojection 64 (Fig. 5) to which is pivoted a lever 65 controlled by a spring 66.

Plate 61 has the same arrangement, and besides to it is pivoted a bell crank lever 67, see Figs. 1, 2, 19 and 19 provided with an adj ustment screw 68. Disks 16 and 16, which are the reverse of each other, see Figs. 1, 2, 7, 13 and 13 have around the periphery elongated openings 69 and guides 70 (Fig. 13) to which are fixed the wire clamping dies 71, which are rovided with a wire guide 72, and a seat 73, fitting the heddle wire and with an offset 74, Fig. 13 to produce an offset in the wire and cause the end of the wire to be even with the main stem of the heddle, as shown in Figs. 24 and 25. Pivoted to disks 16 and 16 are levers (Fig. 13) to which are connected rods 76 passing through springs 77 and pro- 1 i i V groove 120 in it.

. vided with nuts 78. To the levers are fixed the wireclamping dies 79 which swing along 1 guides and enter the die 71, and have an to thedisk flanges by bolts 84.

offset (Fig. 7 13) corresponding to and operating with offset 74.

The central disk 17, see Figs. 1, 2, 8, 9, 14, 14? and 14 has on its periphery semicircular seats 81 Fig. 14 which serve as supports the other which are provided with radial slits88 for the reception of the heddle wire. On the flanges 87, see Figs. 15 and 15*, are pivoted by studs 89, levers 90 provided with tails 91, flanges 92 and heads 93 to which latter are pivoted pieces 94, in which punches 95 are held'in place by a slot 96, a hole 97 and a set screw 98.- A set screw 99, passing through 94 and92, serves to adjust the punch.

' flange 87 is fixed a stud 100 against which i with tails 109 and 110.

i 108 extend into the hollow part 85 of the lever 90 turnson its center 89.

fixedstudslll, (Fig. 9). see Figs. 8 and 8, supports rollers 113 and bears a spring 101 fixed to piece 94, and intended to keep piece 94 in any position as Fixed to the disk 17, see Figs. 14, 14 and 14 and straddling pinions 82 are fork pieces 102 and 103, of which each forms at its lower part a fixed jaw 104 and 105, against which springs 106 press the pivoted jaws 107 and 108 provided The jaws and To disk 17 are also pinion as seen inFig. 14.

The bracket 1 12,

114 and fixed to the bracket is the disk 115,

I which is provided with teeth to turn the 1 pinions, 82 two or three revolutions. 40

The disk 115 has a central hub 115 which serves as a bearing onshaft 10. The bracket 116,

, see Figs. 2,11 and 1l ,with its hub 116, in

which shaft 10 turns freely, supports rollers 117 and 118 and carries on flanges a spring actuated bolt 119 provided with a transverse Secured to the frame (see Fig. 1) are two ormorc brackets 121, which support and journal the horizontalshaft 122 on which,

see Figs. 1, 2, 5, 9, 10, 16 and 16 are fixed a 1' (toothed sector 1.23 (Fig. 10) and a lever 124 supporting an, adjustable weight 125. The shaft 122 also supports and oscillates levers 126,127, and 128 (Figs. 10 and 16). Levers r i 126 and 127, which are fixed to the shaft by set screws, have spring jaws 129 for gripping the wire and transferring it-into the slot of (Fig.18).

the central pinion 82 and on top of pins 49 Lever 128' (Figs. 1 and 16) which .swingsfree on shaft 122, is provided at its 7 upperend with a jaw 130 against which I presses a spring aw131.

Both aws will act I as 81113111 11 for the wire which lies in the slot 88of the pinion the joint between. the jaws 130 and 131, andthese jaws separate to admit punch 95 after it has forced its way between the two members of the duplex wire. A spring 132 and an arm 133, provided with a thumb screw 134 bearing against the frame 1, serve to operate and adjust the lever.

As the pinions revolve about the main axle 10, it 18 necessary at intervals to getthe anvil parts out of the way of the pinions to let them pass. For this purpose the lever 128 is rocked forward out of the swing of pinion 82 and its punching device by the fixed stud 135, against which presses the lever 127 in its forward swing, as shown in dotted lines in Figs. 1. and 16. Two brackets 136 support shaft 137, which operates levers 138 and 139 (Figs. 1, 2, 3, 7 and 13). Figs. 2 and 2 supports a short shaft 141 on which is mounted a cam 142, acting on lever 139. A pinion 143 Fig. 1 on shaft 141 meshes with wheel 11 and is of a size to make either 6 or 3 revolutions to each turn of wheel 11.

A bearing 144 (Figs. 2, 2 and 3) supports a short shaft 145 on which are mounted a cam 146 and a pinion 147 meshing with wheel 11 and of a size to make either 6 or 3.

revolutions to each turn of wheel 11. The 6 Journal 140 or 3 revolutions of pinions 143 and 147 to each turn of wheel 11, refers only to a machine carrying 6 sets of twisting pinions.

Any other number of twisters require different proportional speed. Two brackets 148 (Figs. 2 and 2) support shaft 149 which operates levers 150 and 151 against which latter presses the cam 146. Adjustably supported on the shaft 149 and clamped to the frame, see Figs. 2, 5 and 7, are the pieces 152 and 153 to which are fixed the release pieces 154 and 155 (Figs. 5, 7, and 12 These i 1 i r pieces, see F1gs.5,7 12 ,12 ,12", 12 and 12 have an offset head, provided with circular surfaces 156 Fig. 12 and surfaces 157 and 158, all surfaces corresponding to surfaces 47, 51 and 52 011 the twisting finger and pin.

Two or more standards 159 (Figs. 2 and 5). serve as supports and ournals for shaft 160 on which is fixed lever 161 (Fig. 3) and two movable levers 1 62, carrying movable weights 163. To the levers are pivoted rods 164 carrying at their lower ends bolts 165 (Fig. 5) which pass through slots 63 (Figs. 1 and 18) in plates 60 and 61, and support the bending dies 166 and 167. These bending dies, see Fig. 17, which are the reverse of each other,

have a hole 168, through which passes the supporting and containing the soldering and transfer devices. Two journals 179 Figs. 2 and 3 support a shaft 180 provided with a key 181 (Fig. 5), to keep the movable wheels 182 in alinement. On frame 1 are by suitable devices supported and fixed the parallel and transverse rods 183, 184 and 1.85. The rods 183 support movable troughs 186, Figs. 2, 3 and 5, which are to contain either soldering acid or paste. On the rods 184 are supported small, movable basins 187 and 188 in which solder is to be kept in a molten state by any suitable method, as lamps, electric heaters or the like. To rods 184 and 185 are fixed fingers 189 and 190 (shown in Fig. 2,

' at one place only) of which the fingers 189 press down the heddles and cause them to slide a short distance through the solder, whereafter the heddles will ride up on 190 and leave the solder as finished heddles. A hearing 191 Fig. 3 and standard 192 support and journal shafts 193 and 194. On shaft 193 are mounted three rollers 195 and a pinion 196, Fig. 5. Shaft 194 carries three rollers 197, Fig. 2, rotating on and pressing against top of rollers 195, Fig. 5. On rods 183 and 184 (Fig. 3) slide uprights 198, supporting heddle guides 199 and 200 to which are attached small parallel guides 201 and 202, Figs. 2 and 5 These small guides, see Fig. 5 have a bottom piece 203 and a top piece 204. The bottom piece has an incline 205 which turns the heddle loops to a hori- Zontal position, so they will pass between the guides. The top piece, which is adjustable to suit different wires, has at one end an incline 206 and at the other end a downwardly projecting lip 207 which stops the heddles and causes them to be threaded up on two vertical rods 208, which rods respectively enter the two loops at the end of each heddle. These rods can be arranged in several pairs in a suitable device, so that when one pair of rods is filled up with heddles, the next pair of rods may be moved into proper place. he wheels 178 and 182 and pinion 196 (Figs. 5 and 5 are operated by a chain consisting of links 209 between which are pivoted studs shaped at one end 210 to mesh with the wheels and pinion, and at the other end provided with a finger 211, which pushes along the heddles.

The wire cutting-off device (see Figs. 1, 19, and 19) consists of a block 212 provided with a hole 213 for the passage of the wire.

To said block is hinged the knife 214 which is kept suspended above hole 213 by a spring 215. The cut-off action is as follows; the disk 15 swings around in the direction indicated by the arrow and presses its fixed lever 56 against an offset of the lever 67, which turns on its pivot x and presses down the knife 214, severing the wire. The end wire guide, (Figs. 1, 2 and 21) is provided with a hole 216 and a slot 217 in which fits a cover 218 and 218 leaving a channel for the passage of the wire, as clearly shown. The central wire guide (see Fig. 20) has a flange 219 inclined to suit the upward swing of the griping fingers 129 (Fig. 10) and the top 220 (Fig. 20) is adjustable to suit different wires and prevent heir turning around in the slot formed by the guide. The position of these latter guides is shown at 220 in Fig. 2.

The machine shows six sets of twisters, but any suitable number of sets may be mounted and operated in the same way. All parts in the machine are easy to get at and may be readily adjusted to form heddles of different lengths.

I am aware that many changes may be made by those who are skilled in the art in the construction of my heddle-machine, using certain'parts in different locations and combinations and omitting some parts, without departing from the scope of my invention as expressed in my claims. I do not wish, therefore, that the broad claims which I make herein should be at all limited to specific details of construction.

Operation: I will now explain the various operations of my machine, by which a heddle wire is converted into a finished heddle. The driving pinion 7 turns the wheel 11 and shaft 10 with its several disks and wheels, of which wheel 12 intermittently turns pinion 21 and friction cone 22, which rotates cone 31 and feed wheel 30 causing the heddle wire to to slide through the guides 218, 21.8 and 220. Now the wheel 12 has six toothed parts, each of them sufficient to rotate the pinion 21 one turn, after which it comes to a rest and stops the wire feed, on account of the blank or nontoothed parts of wheel 12. While the wire feeding progresses, the wheel 14, Fig. 10, ro- V tates thesector 123 and swings forward levers 126 and 127 (Fig. 9) until when the wire stops it is gripped by the spring jaws 129. The axle 10 continues to revolve and brings disk 15 (Figs. 2, 5, 19, 19 with tappet arm 56 to bear against the lever 67 which presses down the knife 214 and cuts the wire to the proper length for a heddle. At this moment disks 16, 16 and 17 with their several devices have swung into position for springs 66 (Fig. 5) to press levers 65 under the twisting fingers 45, to hold them and prevent their displacement one of the blank or untoothed spaces on wheel 14 (Fig. 10) releases sector 123 and allows the lever 124 with its attached weight 125 to turn the shaft 122 and rock lever 126 and 127 (Fig. 9) backward. This brings the wire into the slot of central pinion 82 and between the jaws 104 and 107 (Figs. 14, and 14 and and 108 (Fig. 14) and at the same time each wire end is slid on top of loop-forming pins 49 (Fig. 18) and is slipped into die openings 73 (Figs. 13 and 18). While the fingers still hold the wire, the lever 127, Fig. 9, hits the tail 91, Fig.

,ai1d rocks the lever 90, until the punch 95 presses'between the two members of the lever-139 (Fig.2) which controls shaft 137 and levers 138 (Fig. 7).

A press down the levers 162 operating the ending dies 166 and 167, Figs. 1, 17 and 18,

'The pinion. 7 has two toothed sections between the blank spaces each turning the Wheel llone sixth of a revolution; but the blank space having swung past, the pinion 7 again starts the wheel 11, turning the pinion 143 (Fig. 3) and disengaging cam 142 from The lever 139 being free, the levers 138(which have pressed 7 I against levers 75 and held dies 79 (Fig. 13)

out of 'theway of the wire) now swing back, and, actuated by springs 77, the levers 75 swing and press the dies 79 against the wire,

'thus claniping it for twisting the heddles.

At the same time the disks 16, 16 and 17 (Fig.2) have swung slightly up and the clamping jaw tails 109 and 110, (Figs. 14

' and 1.4") have become disengaged from rollers 117 and 113(Figs. 8 and 11") by which theywere l'ieretofore-pressed in to open jaws 107 and 108 for the entrance of the wire.

- Thewire being clamped at the end loops and on both sidesof the'center eye, it is ready for twisting, which is accomplished by the centralfpinion '82 and end pinions 42 engaging with the geared portions of disks 115 and ,62, Figs. 6 and 8, 'which turn the pinions two or three revolutions.

'12 0' pieces .152 and 153, Fig.2,withdrawing thepins 49, Figs.12 and 18 from the heddle loops and the heddle, coming in con tact with the inclined faces of release ieces 1.52. and 153, Figs. 5, 7jand 12 the he( dle is pressed out of die 73, Fig. 13, and slides down i 7 onto the transfer chainj211. The circular face 156, Fig. 12, fits the circular recess 47 and prevents the twisting finger from turning on its own axis during the time the pin 49 is being withdrawn from the heddle loops by the pressure of planes 157 and 158 against planes 51 and 52. When the heddle is free, the cam 146, (Figs. 2, 2 and 3) disengages lever 151. which controls shaft 149 and allows the levers 150, Fig. 7,-to clear levers 75 which swing back to their normal or closed positions, to be 0 ened again by contact with levers 138, *ig. 13. Carried by the transfer chains the heddle passes between the rollers 195 and 197, Figs. 2 and 5, which treat it with acid or soldering paste at the twisted places where solder is to be applied, and then it passes to the solder basin, where the fingers 189 cause the heddle to slide through the solder for some distance, and it then rides up on the fingers 190 and leaves the solder. The heddle is now finished and is carried along in guides 201, 202, 203, and 204 in which it slides until it stops against lips 207 and its loops are threaded onto rods 208, as seen in Figs. 5 and 25. The heddle is shortened slightly during the twisting process and would break if no precaution were taken to prevent it. Now the spring disks 43 at the ends of the twisting pinions (Fig. 2) compensate for said shortening of the heddle by allowing a slight longitudinal movement of the shafts 41 which carry the twisting fingers. Said shafts are provided with a small key sliding in a keyway cut in the pinions.
